In a recent study published in Physical Review Applied, scientists at the US Department of Energy’s Brookhaven National Laboratory have developed a new, simple, efficient and highly customizable method for changing laser colors.
Dynamic optical beam-steering of a band-edge chiral nematic liquid crystal (LC) laser has been demonstrated, achieved through the use of tuneable nematic LC phase shifters and fixed polarisation gratings.
In this article, we will explore the principles behind pulsed dye lasers, their advantages and limitations, as well as their diverse applications in various fields.
Multiphoton lithography is a cutting-edge technology used to create intricate three-dimensional structures, such as those found in microelectronics.
A monolithic silica fiber laser operating at 585 nm has been developed and is being reported for the first time.
A team of researchers have achieved a maximum of 1.7 W at 540nm using a self-frequency-doubling green laser in Nd3+-doped La2CaB10O19 (Nd:LCB) crystal by utilizing the energy level splitting of Nd3+ ions.
A group of scientists from Japan have developed a new type of Distributed Feedback (DFB) laser that can transmit data at speeds of 200 Gb/s over a record distance of 10 kilometers.
Laser pointers are a popular tool for presentations, pointing out objects at a distance, and even as a toy for pets. However, it is important to understand the science behind laser pointers before making a purchase.
A supercontinuum laser is a type of laser that generates a broadband spectrum of light. This spectrum extends over a wide range of wavelengths, from the ultraviolet to the infrared region. The term “supercontinuum” is derived from the fact that the laser’s spectrum is continuous, unlike that of a typical laser, which is typically limited to a narrow range of wavelengths.
Two-photon excitation, a unique form of light-matter interaction in which two photons are absorbed simultaneously by a material, is one such interaction that has a wide range of applications.
